It is Valentine's Day. For everyone that forgot, you better go out and do something.
I came across this wonderful link from Amazon. The title for the page is "Valentine's Day: Bad Gift Ideas"
Now mind you, it is too late to order this year but you could plan for next year! Of course, you may not have a significant other after you deliver the present you ordered.
I try to stick with the basics. A card or candy or flowers or any combination. I would strongly suggest you consider a gift she would like and then take some time to laugh about the gifts you could have bought at Amazon instead.
"I love you also works on Valentine's Day."
